Even in well-equipped courtrooms, video trial presentations are a pain. There’s figuring out what equipment they have versus what you have to haul into the courthouse, making sure connectors are compatible, coordinating between your tech people and theirs … in short, a pain.

But Google’s announcement of the Chromecast app and device Wednesday morning may start making video trial presentations a lot easier. And, miraculously, without breaking the bank.

Google Chromecast is a $35 dongle that connects to any HDMI port (television screen or computer monitor), finds a Wi-Fi network, and allows the user to broadcast from an Android device to the television/monitor. Youtube and Netflix interfaces will allow you to hit a single button and forward that video to the television/monitor, too. Google Music streaming to the television is also supported.

So … no more projectors? No more cables? No more compatibility issues? Maybe:

First, Chromecast is affordable. For a modest amount of money, users can connect devices to televisions and present information to juries or clients. The product seems to require very little technical knowledge, thereby making it easy-to-use. And finally, it’s a cross-platform product, which means that iOS lawyers won’t need an expensive Apple TV to run TrialPad, and Android users can use their devices to present information.
